    Adding fisheye to dahua NVR - 1 channel, not 4 ?

    Updating to a newer 16 channel "VIP Vision" NVR (rebadged dahua, I think). Everything's fine until a Hikvision 12MP fisheye: ONVIF works, but it keeps auto-adding 3 additional virtual channels as well, instead of just the single main fisheye stream I want. I can't see any way to disable the...

    Hikvision Config / Login - javascript woes

    Camera: DS-2CD2332-I Firmware: V5.2.0 build 140721 It seems that in the old IE browser, the login process has a javascript bug, so I can't login (name and password is correct, just the login button never triggers). But if I use a more modern browser (Chrome/Edge) the login javascript works...

    Mounting multiple 940nm LED bulbs

    in short - My question is whether anyone has any experience or even just ideas on the best way to mount a lot of fiddly little LEDs. Right now I have a kind of writer's block on how to put this together from a DIY perspective. As background / explanation - I've tried the IR lights in my...

    DS-2CD3345F-I, Language Mismatch and No Resource

    Putting together the following NVR and cameras - 1 x DS-7804N-K1/4P NVR running v3.4.90 (English, hacked) firmware. 3 x DS-2CD3345F-I cameras running v5.5.12 (Chinese) firmware. Language Mismatch (solved) Tried Hikvision and ONVIF protocols, but they show language mismatch. Bit surprised at...

    Reset button for Hikvision turret? (DS-2CD2335-I)

    Any pointers on where the reset button is on the DS-2CD2335-I ? Trying to get it back online with a factory reset and not having much luck. I saw the thread below as well as a teardown, but newer cameras don't seem to have the same innards? hikvision ds-2cd2032-I unreachable after port change...

    Lens change on DS-2CD2335-I ?

    Two questions: 1. Does anyone sell the genuine Hikvision 2.8mm lens for this camera? 2. Has anyone done a lens change? Is it very complicated? I saw some tear-downs that look like I could accomplish - I've wired my house with cat6 and done hardware changes on servers, PCs and laptops in the...

    Number plates - more megapixels? lens choice? settings?

    I'm very satisfied with Hikvision, including several good outcomes after thefts. Each time I was asked if there was "a better view of the number plate?". I'm not permitted to post imagery but suffice to say I'm struggling to improve the footage. Vehicles are only between 10-15 metres from the...

    Criteria for "Non-LAN only" ?

    From the BI help file... "If you select to authenticate Non-LAN connections only, users connecting from within your local home/office network will not be prompted, while those connecting from the Internet will be prompted." So, does BI use the source IP being part of the standard private...

    Multi-camera playback (for Alerts)

    Finally got my v4 platform up - amazing how the CPU usage goes down when you have a decent CPU and present-day o/s. ;) For some reason I thought playing back Alerts would display all my cameras - do I need to make a camera group or something for that, or is it not yet a feature? I wouldn't...

    Hikvision NVR with POE ports - bridge to LAN interface?

    From what I've read, the POE ports on the back of the NVR (e.g. DS-7604NI-SE/P) are isolated from the LAN segment that the NVR itself is connected to. What are the chances of the POE ports ever being bridged with the internal LAN interface? I'd really prefer to be able to reach the IP cameras...
